Yaxx1 is a Perl script that facilitates batch data
processing using Perl open source software and commonly available software
such as CIAO/Sherpa, S-lang, SAS, and FTOOLS. For Chandra and
XMM analysis it includes automated spectral extraction,
fitting, and report generation. The primary emphasis is on having a simple
tool that can be run without requiring an extensive learning curve.
However, for those with the motivation, yaxx is highly
configurable and can be customized to support complex analysis. In
particular yaxx uses template files and takes full advantage of
the unique Sherpa / S-lang environment to make much of the
processing user configurable.

Although originally developed with an emphasis on X-ray data analysis,
yaxx has evolved to be a general-purpose pipeline scripting
package. The current development version of yaxx has been
substantially refactored to separate the core pipeline functionality from
the specific analysis threads. Scientists doing repetitive
and scriptable data processing will find benefit from the functionality
provided by yaxx.

NEWS (2013-Apr-06): Yaxx is NO LONGER SUPPORTED and
will not work with recent versions of CIAO. This page is
maintained only for archival reasons.

Presently Yaxx supports Linux, Mac OSX, and Solaris 2.8 platforms.

Yaxx has been developed by Tom Aldcroft with support from
NASA under NASA grant NAS8-39073 and CXC archival research grant
AR2-3009X (ChaMP collaboration).
